I've just bought this a Kiddopotamus Swaddleme on the recommendation of a friend. It's the right one for my 15 week DS weight etc. But the swaddle itself seems really, really snug. (it has the pocket for the baby, the strips that go over and attach by velcro).
It worries me a bit. Can a swaddle be too tight and cause harm? My friend says the fabric stretches with them and they like it...but it still worries me a bit.
